I had a working Optiarc AD-7740H with a flashed 1s0 firmware. The drive recently stopped working. I bought a new AD-7740H (from eBay) but it has a c842 firmware version. I want to flash it with something with booktype, riplock, RPC1 and/or auto-reset.
Would it work if I crossflash with any version (maybe a842) or must it be a version of c842?
